Method and system for a centralized vehicular electronics system utilizing ethernet with audio video bridging

Abstract

Aspects of a method and system for a centralized vehicular electronics system utilizing Ethernet with audio video bridging are provided. In this regard, electronic devices in a vehicle may be communicatively coupled via one or more Ethernet links and information may be communicated between the electronic devices over the Ethernet link(s) utilizing audio video bridging. At least one of multimedia, control, diagnostic, and sensory information between the electronic devices. Accordingly, resources on the one or more Ethernet links may be reserved via AVB to give priority to one of multimedia, control, diagnostic, and sensory information. Information communicated between the devices may be secured utilizing MACsec and related protocols. The electronic devices may comprise two or more network ports and may be enabled to forward packets between the two or more ports. The Ethernet links may comprise optical and / or copper cabling.

AI Technical Summary

Benefits of technology

The invention is a system and method for a centralized electronics system for vehicles that uses Ethernet and audio video bridging. The system allows for the efficient and effective control and management of vehicle electronics. The technical effects of this invention involve improved efficiency and reliability of vehicle electronics systems.

Problems solved by technology

Consequently, installation and interoperation of the various electronic components is becoming increasingly complicated and expensive.

In this regard, the wiring alone required for communicating data to and from the various electronic devices is a major source of cost and complication in a vehicular electronic system.

In this regard, specialized physical media, as is conventionally utilized in the vehicular industry, may be expensive.

Additionally, existing standards for vehicular networking, such as MOST and IDB-1394, are immature and largely unproven at high data rates.

Additionally, non-standardized devices, connectors, and / or protocols utilized by vehicular electronics networks may further add to the cost and complexity.

Thus, conventional and traditional vehicular electronics system may be expensive, complicated, and difficult to upgrade.
